Abstract
The utility model discloses a sheet-fed printing press downswing type front lay mechanism. The sheet-fed printing press downswing type front lay mechanism comprises a driving swing arm, a first connecting rod, a first swing rod, a second swing rod, a second connecting rod, a front lay swing arm and a front lay cam, wherein one end of the driving swing arm is hinged with one end of the first connecting rod, the front lay cam used to provide driving force is arranged between the driving swing arm and the first connecting rod, the other end of the first connecting rod is hinged with one end of the first swing rod, the other end of the first swing rod is connected with one end of the second swing rod through a cylindrical pin, a whole body composed of the first swing rod and the second swing rod can rotate around the cylindrical pin, the other end of the second swing rod is hinged with one end of the second connecting rod, and the other end of the second connecting rod is hinged with the front lay swing arm. According to the sheet-fed printing press downswing type front lay mechanism, the cam and the swing rods move through two sets of four link mechanisms so as to achieve the effects of not only enabling a front lay to rapidly avoid paper but also not enabling the lift range of the cam to be large, and therefore the sheet-fed printing press downswing type front lay mechanism has the advantages of being strong in movement and power performance, suitable for high speed running and the like.
Description
Technical field
The utility model discloses pendulum-type front lay mechanism under a kind of sheet-fed press.
Background technology
The paper positioning device of sheet-fed press is called again well-behaved mechanism, its effect is that paper to be printed was accurately located before impression, the paper that guarantee is transported to printing equipment has a fixing correct position with respect to forme, thereby makes to accomplish that chromatography is accurate between paper and paper, look and look.Longitudinal register is completed by front lay mechanism, and located lateral is completed by side mark square mechanism.Rule mechanism is as the vitals of sheet-fed press, structure, the accuracy of manufacture, motion and the dynamic characteristics of its mechanism is directly connected to the speed of printing machine, the chromatography precision of printing, all the time be the manufacturing research emphasis of domestic and international printing machine, be always subject to the manufacturing great attention of domestic and international printing machine.
According to the technological action of front lay (upper pendulum is prepared splicing, above stops paper location, and the bottom is by paper, under stop returning immediately), if front gauge mechanism is directly made up of cam swing mechanism.So, allow rapidly paper in order to realize, the lift of respective section cam is very large, and curve is very steep, and transmission pressure angle is very large, causes the motion of mechanism, power performance poor, is not suitable for high-speed cruising, therefore, and this case and giving birth to.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one can make front lay allow fast paper, does not make again pendulum-type front lay mechanism under the excessive sheet-fed press of driving cam lift.
The utility model deal with problems adopt technical scheme be:
Pendulum-type front lay mechanism under a kind of sheet-fed press, comprise initiatively swing arm, first connecting rod, the first fork, the second fork, second connecting rod, front lay swing arm and front lay cam, one end of described active swing arm and one end of first connecting rod are hinged, and initiatively between swing arm and first connecting rod, be provided with the front lay cam as driving force, one end of the other end of first connecting rod and the first fork is hinged, the other end of the first fork is connected by straight pin with one end of the second fork, and the entirety of the first fork and the second fork composition can be rotated around straight pin, the other end of the second fork and one end of second connecting rod are hinged, the other end of second connecting rod and front lay swing arm are hinged.
Further setting as such scheme: described straight pin is fixed on printing machine body.
Further setting as such scheme: described front lay swing arm rearward end is fixed on printing machine body.
Further setting as such scheme: described active swing arm rearward end is fixed on printing machine body.
The beneficial effects of the utility model are:
The utility model cam swing move through two cover four-bar mechanisms, initiatively swing arm only need be put less angle, front lay swing arm just can be put sizable angle, by such Mechanism Combination, just can realize and can make front lay allow fast paper, not make again driving cam lift excessive, therefore, there is motion, power performance is strong, is applicable to the advantage such as high-speed cruising.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model provides pendulum-type front lay mechanism under a kind of sheet-fed press, comprise initiatively swing arm 1, first connecting rod 2, the first fork 3, the second fork 4, second connecting rod 5, front lay swing arm 6 and front lay cam 7, one end of one end of described active swing arm 1 and first connecting rod 2 is hinged, and initiatively between swing arm 1 and first connecting rod 2, be provided with the front lay cam 7 as driving force, one end of the other end of first connecting rod 2 and the first fork 3 is hinged, the other end of the first fork 3 is connected by straight pin 8 with one end of the second fork 4, and the entirety that the first fork 3 and the second fork 4 form can be rotated around straight pin 8, one end of the other end of the second fork 4 and second connecting rod 5 is hinged, the other end of second connecting rod 5 and front lay swing arm 6 are hinged.
Described straight pin 8 is fixed on printing machine body.
Described front lay swing arm 6 rearward end are fixed on printing machine body.
Described active swing arm 1 rearward end is fixed on printing machine body.
When work, front lay cam 7 drives initiatively swing arm 1, initiatively swing arm 1 drives first connecting rod 2 to move downward downwards, first connecting rod 2 drives the first fork 3 to move downward, because first fork 3 one end are connected by straight pin 8 with one end of the second fork 4, and the entirety that the first fork 3 and the second fork 4 form can be rotated around straight pin 8, and therefore the second fork 4 drives second connecting rod 5 to move upward, thereby drive front lay swing arm 6 to swing.
The utility model cam swing move through two cover four-bar mechanisms, initiatively 1 need of swing arm were put less angle, front lay swing arm 6 just can be put sizable angle, by such Mechanism Combination, just can realize and can make front lay allow fast paper, not make again driving cam lift excessive, therefore, there is motion, power performance is strong, is applicable to the advantage such as high-speed cruising.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
